Area Code 4143 – Berdychiv, Zhytomyr

Overview of Area Code +380 4143

Area code +380 4143 is a geographic destination code within the Ukrainian national numbering plan, assigned to the city of Berdychiv and the surrounding districts of the Zhytomyr Oblast. As a fixed-line code, it routes calls to the public switched telephone network (PSTN) infrastructure operated by local telecommunications providers. The code follows the ITU-T E.164 international standard, ensuring global interoperability.

Geographic Coverage and Administrative Jurisdiction

Berdychiv is a historic city located in the northern part of Ukraine, approximately 180 kilometers southwest of Kyiv. It serves as the administrative center of the Berdychiv Raion within the Zhytomyr Oblast. The area code covers the city itself and the adjacent rural settlements that rely on the same local exchange. The region is known for its industrial base and cultural heritage, including the Carmelite Monastery and the former Berdychiv Fortress.

Dialing Formats and Caller Instructions

For domestic callers within Ukraine, the local dialing format is 04143 followed by the subscriber number, typically five to seven digits long. When calling from abroad, the international format is +380 4143 followed by the subscriber number. For example, a local call to a Berdychiv number might be dialed as 04143 2 34 56, while an international caller would dial +380 4143 2 34 56.

Callers from outside Ukraine must replace the international access prefix (00 or +) with the appropriate exit code for their country. For instance, from the United States, one would dial 011 380 4143 followed by the number. It is essential to omit the leading zero of the domestic trunk prefix when dialing internationally.

Overlay and Numbering Considerations

As of the latest ITU-T and Ukrainian regulatory updates, there is no overlay code for Berdychiv; the area code 4143 remains the sole geographic code for the city. However, subscribers may have the option to port their numbers to alternative fixed-line operators, which does not affect the geographic significance of the code. The number length after the area code is typically six digits, but some older lines may have five or seven digits depending on the exchange capacity.

Practical Usage for Local and Foreign Callers

For local callers, dialing the area code is mandatory even for calls within the same city, as per Ukrainian regulations. For foreign callers, it is crucial to verify the correct subscriber number length, as it may vary. The code is used for both residential and business lines, including government offices, commercial enterprises, and private subscribers. VoIP and mobile users should note that calls to this code are treated as fixed-line calls and may incur different tariffs compared to mobile numbers.
